| Zusammenfassung: | A power managing system and method are provided. When an under voltage lockout circuit determines that a common voltage of the power managing system is smaller than a first lockout voltage, the under voltage lockout circuit outputs a first under voltage lockout signal for controlling one of a plurality of power converters that supplies a maximum output voltage to quickly reduce their output voltages to zero values. Then, the under voltage lockout circuit outputs a second under voltage lockout signal for controlling another one of the power converters that supplies a minimum output voltage to gradually reduce its output voltage to a zero value. |
